Two standard frames are available as detailed below, although we are able to manufacture bespoke options (minimum section for fire rated frame is 70x32mm). Frames can be manufactured from softwood or hardwood, with full factory polish or primed ready for final site decoration.
Frames are pre factory assembled, using a traditional mortise and tenon joint, generally intumescent seals are pre fitted to the frames. Frames are usually manufactured from a solid section up to 140mm. For walls wider than this, an extension lining is incorporated as detailed below.
